Clarification on Shor's algorithm qubit requirements — did I understand this correctly?
Below-threshold error correction is a critical step toward fault-tolerant quantum computing, but scalability remains a major hurdle for both superconducting and topological approaches.
Summarize this article with:
I've been researching the recent breakthroughs in quantum computing and wanted to get this community's take. Google's Willow chip (105 qubits) just demonstrated below-threshold error correction for the first time. Microsoft claims their topological approach with Majorana 1 could scale to a million qubits. Two questions for discussion: Which architecture do you think reaches fault-tolerance first? What's your realistic timeline for Shor's algorithm breaking RSA-2048? I put together a detailed overview comparing both approaches and their implications for encryption. Happy to share the link if anyone's interested, but mainly looking for perspectives from people actually working in this space. submitted by /u/Only_Bath697 [link] [comments]
